Abstract

Community Service activities aim to provide skills to partners in developing interactive multimedia-based learning materials. The method used is the approach method which includes observation, interview and counseling. The implementation of this activity was carried out in two meetings or about two days, where the meeting was in the form of presentation of material, and continued with assistance in making multimedia-based learning materials until completion. The results obtained by participants can create interactive learning media with the Sothink SWF Easy application. The response results from participants gave positive statements.

Abstract

This research utilizes the Rapid Application Development (RAD) approach, with the analysis stage involving a review of relevant literature and interviews with prospective system users. The next stage is the requirement planning, which entails defining the features or services within the software accessible to prospective system users. The design phase employs use case diagrams, activity diagrams, and Entity Relationship Diagrams (ERD). Subsequently, it is translated into the Laravel framework and undergoes testing to produce a software system for assessing Graduate Learning Outcomes (CPL). This system offers facilities for academic programs to create outcome-based education (OBE) mappings and enables instructors to assess students based on the established mapping data. It also provides students with the ability to view their outcome results. CPL refer to the essential skills that students must acquire following their academic studies. These skills encompass the internalization of grades, attitudes, general knowledge, and specific skills, which students are required to fulfill throughout their academic journey. Outcome grades, as mapped, are attained by students through participation, written tests (quizzes), observations (practical exercises), performance (presentations), mid-term exams, final exams, and oral tests (group assignments). This Graduate Learning Outcomes assessment software is expected to assist program administrators and instructors in managing CPL and also enable students to access detailed records of their outcome grades.

Abstract

The development of information technology in the digital era has influenced various aspects of life, including library services. Along with these technological advancements, libraries are required to develop technology-based services through the implementation of digital library automation systems such as INLISLite to improve the quality of information services.This research was conducted at the library of SMA Methodist 3 Palembang, which still used a manual system for managing borrowing, returning, searching, and cataloging books. As a result, delays and data recording errors frequently occurred. In addition, unstructured data storage made library management less efficient. Therefore, the development and integration of an INLISLite-based digital library automation system were carried out to assist in managing book collections, member data, borrowing and returning transactions, fines, and library reports in a more effective and structured manner.The benefit of this research is to support the creation of a library that continuously adapts to technological developments and provides better services to its users. This study employed the Research and Development (R&D) method, consisting of data collection, planning, development, testing, and product refinement stages. The results of this research are expected to improve the effectiveness, efficiency, and quality of information services in the school library

Abstract

Student data at vocational high schools is managed solely by the schools, so external parties must contact the school to confirm a record, while account access still relies on passwords vulnerable to credential theft. This study implements a Self-Sovereign Identity system for student academic data at SMK Bina Sriwijaya Indonesia Palembang that combines passwordless WalletConnect authentication with credential issuance, verification, and revocation anchored on a public blockchain. Following the Design Science Research Methodology, the artefact was built as a web prototype using React.js, Express.js, and PostgreSQL, connected to MetaMask and to a CredentialRegistry smart contract on Ethereum Sepolia. Users authenticate through an EIP-191 challenge-response signature, student identity is expressed as a did:ethr Decentralized Identifier, and academic data is issued as W3C Verifiable Credentials whose canonicalised Keccak-256 hash and status are recorded on chain, while the complete record remains off chain. Evaluation covered four levels: eighteen black-box functional cases, thirty smart contract unit tests, seventeen backend tests, and fourteen security cases at the authentication and verification boundary, plus gas measurement of every state-changing function on Sepolia. All seventy-nine cases produced the expected output, which demonstrates functional conformance and correct access control rather than a general guarantee of security, since independent penetration testing and a formal contract audit were not performed. Within these limits, a verifier can check authenticity, issuer, and validity independently, without confirmation from the school and without exposing personal data on a public blockchain.
